' T all whom it 1mg concern:

Be it known that I, Eccnn'r H. GOLD, a citizen of the United States,residing at Chicago, in the county of Coolnand State of Illinois, haveinvented certain new and useful Improvements in Heating Systems, ofwhich the following is a specification;

T he invention relates to a heating system particularly adapted forrailway cars in which steam is taken from a source of hi h pressure,wh1ch,'however, may be variable, as 15 the pressure in the tram plpe incar heating systems, and circulated at a lower uniform ressure throughsuitable coils or other radiating devices.

One of the principal objects of the invention is to control by a singlecontroller a. plurality of coils or radiators such a way that one ormore of such radiators may be closed without interfering with themaintenance of the desired conditions in the remaining radiators.

vide means for keeping the. thermostat at a non freezing temperature.regardless of whether said radiators are open or closed.

I accomplish these urposes by interposing between the source 0 so plyand the radiator or radiators a controlling device comprising an inletvalve and a thermostatic membcr for operating the same and providingalso a conduitwhich leads from the low ressur'e side of the inlet valveinto proximity with the thermostatic member of the controller, thisconduit having a valve which can be set toregulate the flow of fluidtherethrough.

The present application relates particularly to an arrangement in whichthe conduit referred to has no efiective heating function and to anarran ement in which such conduit, whether it as this function or not,is interposed between the common supply pipe of a plurality of radiatorsand the thermostatic member of a single controlling device whichcontrols the flow of heating fluid to said radiators. The broaderfeatures'of the invention herein disclosed are claimed in my co-pcndingapplication, Serial No. 299,529, filed February 5, 1906, this applicatiobeing a division of such prior application.

The invention is illustrated in the accompanying drawings, whereinIfigore 1 is a perspective view of one form of heating system suitablefor carrying out A further object of the invention is to prothrough thecontrolling device, and Fig. 3 a sectional plan on line 3-3 of Fig. 2.

Like characters of reference indicate like parts in the several figuresof the drawings. Referring to the drawings, A represents the train pipeor other source of supply of steam at high pressure.

The controlling device is represented generally by the letter B.

C, D, E and F are radiating coils which preferably discharge freely tothe atmosphere and maybe of different length shown. The coils might, ofcourse, be of the same length. a

G is a common supply pipe which sup lies all of the radiators with steamtaken tom the train pipe A and maintained at a uniform lower pressure bythe agenc of the controlling device to be describe hereinafter. i H is aconduit or loop which leads from trollor B.

Any desired form of thermostatic con trollor may be employed forcontrolling the inflow from train pipe A in accordance with thermostaticconditions at the discharge end of loo H. I have shown a suitable formof contro ler in Figs. 2 and 3. This dc ice comprises a casing which isdivided so as to form a high pressure chamber 5 with which the trainoipe A communicates, and a low pressure 0 amber 6 between which is aport controlled by a valve 7; and a chamber 8. In the bottom of thecasing is tapped a pipe 9 to which is screwed a casing 10 in which islocated a thermostatic member 11 consistiu of a receptacle containing a"olatile fluif. Resting on the thermostatic memheris asrod 12, thereduced portion of which 13 engages with a lever 14 on a rock shaft '15,carrying a lever 16 which similarly engages with the stem 17 of valve 7.The rock shaft mav pass the invention. Fig. 2 a vertical section.

pipe G to the thermostat chamber of condinary manually operated globevilla-e20.

Any other sort of valve might. be employed. The thermostat has the usualad usting screw 31.

The separate radiators are preferably provided with the restrictingvalves 22 which may be adjusted as required. The radiators may also havethe manually operated valves by means of which they may .be closedagainst the inflow of steam.

The operation of the heating system described is as follows: The steamfrom train pipe A flows-into low pressure chamber 5 and thence pastvalve 7, supposin this valve to be open, and into supply pipe Supposingvalve 19 to be open the steam will pass from pipe G into such of theradiators as are open in amounts determined by the relative positions ofvalves 22, which valves are ordinarily set so as to maintain the desiredamount of steam for the particular radiator. Preferably, these radiatorsare open to the atmosphere at their discharge ends so that the pressurein them does notrise above atmospheric pressure. The vosume of steam inthe radiators will obviously depend upon the position of valves 22. Thesteam from supply pipe G will also pass through loop H to the thermostatand if in suflicient volume, will act upon the thermostat to cause'theclosing or throttlingpf valve 7. The amount of steam passing to thethermostat may bedctermine by a proper settin of valve 20. It will beseen, therefore, that the controlling means is of-such a character as toaccommodate itself automatically to variations in the amount ofradiating surface under steam.

- If one of the radiators is closed, this causes a rise in ressure inthe supply pipe and consequent y a rise in pressure inloop resulting ina shutting down of valve. 7. The pressure in the common supply pi e G isconsequently automatically ad uste so that there is no excess in theremaining radiators, and cons uently no loss of steam. If valve'19 beclose or if all the separate valves 23 be closed, valve 19 being-merelyfor convenience in shutting off the whole system, there will stillenough steam pass to.

the thermostat to keep it at a non-freezing temperature in cold weather.I

It will be understoo' that the various valves will be set so as toadjust the System to Iarg particular requirements.

not limit myself to the particular devices, constructions andarrangements shown, as modifications might be. devised which would comewithin the inventipn, as defined by the claims. I do not, however, claimthe inventions claimed in my prior application referred'to above,intending in the present application to'claim suohinven- ,tions specificto the arrangements here. shown which are not claimed in the priorapplication.
